Melanie Sykes and gene expert Anthony Adolph present a series that finds relatives who have been missing from a person's life and reunites them. They track down three possible relatives who must undergo a series of intense genealogy tests, as only then can the real relative be identified.

He's lived as an only child for over 60 years and knows he has brothers and sisters out there somewhere. The Gene Detectives find three possible sisters and use the latest computerised 3D face maps and DNA tests to compare their genetic ancestries.

Colin's never seen his sister, so will he be able to choose through instinct or will the science help him decide? Plus, tips on tracing your own family tree. Show less
